  • Percentage of Records

Default Value: Number of Records

Example: Percentage of Records
Number of RecordsString/ExpressionSampling Type is Number of Records

Enter the number of records to output.

Info

The ELT Sample Snap outputs the entire table if the total number of records in the table is less than the value specified here.

Default Value: NA

Example: 10
Percentage of RecordsString/ExpressionSampling Type is Percentage of Records

Enter the percentage number of records to sample your data based on a percentage value of the total records in the table.

Info
  • The number of records in the output is rounded off to the lower value if the percentage leads to a decimal. For example, if you enter 75 and if the table has 10 records, the output yields 7 records since 75% of 10 is 7.5.
  • The number of records in the output is randomized and is up to a maximum of the percentage calculation specified above. Therefore, in the above instance, the output may contain 5, 6, or 7 records.

Default Value: NA

Example: 25
